Error
Inrush resistance

Occurs when the
main circuit power
supply is turned ON.
Inrush current when
the main circuit pow-
er supply is turned
ON exceeds inrush
resistor tolerance.
Reduce the frequency by
which the main circuit
power supply is turned
ON and OFF.
Occurs when the
control circuit power
supply only is turned
ON.

is turned ON.
Absolute encoder
backup voltage has
fallen.
Occurs the first time
the encoder is used.
Set up the absolute en-
coder correctly.
Checksum error
(ABS)
Occurs when control

Set up the absolute en-
coder correctly.
Battery error (ABS) Occurs when control
circuit power supply
is turned ON.
Absolute encoder
battery voltage has
fallen (to 2.7 V or
less)
Replace the battery while
the control circuit power
supply is ON.
Absolute error Occurs when control
circuit power supply
is turned ON or dur-
ing operation.
Absolute encoder
sensor check error
(internal encoder er-
ror)
Turn OFF the power sup-
ply, then ON again.
Take noise countermea-
sures.
Replace the Servomotor
(if the cause is encoder
error).
Encoder is defec-
tive.

Servo Driver is de-
fective.
Replace the Servo Driver.
Overspeed error
(ABS)
Occurs when control
circuit power supply
is turned ON.
Servomotor is rotat-
ing at 200 r/min. or
more when the con-
trol circuit power
supply is turned ON.
Turn ON the control cir-
cuit power supply while
the Servomotor is OFF.
